IMMUNITY TEST WAVEFORM GENERATING DEVICE AND IMMUNITY TEST WAVEFORM GENERATING METHOD

摘要

PROBLEM TO BE SOLVED: To generate an immunity test waveform for switching noise of a switching power supply using pulse-width modulation.;SOLUTION: According to one embodiment of the present invention, there is provided an immunity test waveform generating device. The immunity test waveform generating device includes a waveform generator. The waveform generator generates an immunity test waveform for switching noise of a switching power supply on the basis of at least one of a waveform of first type which is a repetition of damped oscillation in which an oscillation frequency fluctuates periodically and a waveform of second type having been subjected to both amplitude modulation and frequency modulation.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
